Answer:
VW ≈ 4.0
Step-by-step explanation:
Using the sine ratio in the right triangle
sin35° =
=
=
( multiply both sides by 7 )
7 × sin35° = VW , then
VW ≈ 4.0 ( to the nearest tenth )
Answer:
Puppy Liz runs 34.61 ft.
Step-by-step explanation:
From the figure we can extract two triangles: one with angle 34° and adjacent 40ft, the other with angle 34°+23° and adjacent 40ft.
Let us call the distance from the pole to the fire hydrant
, and the distance from the pole to the bench
, then the distance
from the fire hydrant to the bench is

which is the distance the Puppy Liz runs.
Now, from trigonometry we have

and


Therefore, the distance
Puppy Liz runs is


Answer:
9p2 + 6p - 8 -12 = <em><u>9p^2 + 6p -20</u></em>
Step-by-step explanation:
You can't change 9p^2 or 6p as we do not know what p is equal to but
-8 + (-12) = -20
So if we put it all together we get <em>9p^2 + 6p -20</em>
